MOTIVE POWER.

of ditto, taken in the plane indicated by the line w. m. Fig. 1. 1Similar letters of reference in both views indicate corresponding parts.

.The only power which is at the command of man at leastduring alargepart of the time, and which involves no expense except the cost ofmachinery and of keeping the same in repair, is the power of the wind,and if this power was steady and continuous, a cheaper motive powercould not be de-. vised. The difficulty with wind wheels is that in somecases, when a strong wind prevails, an unnecessary amount of power isexpended and in other times, when the wind lulls or goes down, only aslow motion or To amend this difiiculty and to store up the surpluspower of a wind wheel when a high wind prevails so as to be abletoproduce a uniform and continuous rotary motion, is the object of myinvention, which consists in the combination with a wind wheel of abucket wheel to be operated by a series of balls of stone or other heavymaterial which are conducted to the wheel through long inclined channelsand which after having descended, are elevated by the action of the windwheel whenever the wind has sufiicient power to produce a motion of thesame, and of the elevator, which serves to raise the balls.

To enable those skilled in the art to make and use my invention, I willproceed to describe its construction and operation with reference to thedrawing.

The bucket wheel A. to which a continuous and uniform rotary motion isto be imparted, is secured to a shaft 64. from which the motion istransmitted to the working machines or to the desired place, by means ofa-cog wheel I). or in any other desirable manner. The bucket wheelderives its motion from the gravity of a series of balls 0. of stone orother heavy material, which are conducted to the buckets throughinclined channels B. similar to an overshot water wheel, and as thewheel turns, it discharges one ball after the other into channels B. a

guard d. being provided to prevent the premature discharge of any of theballs:

The channels B. B. must be made sufliciently long to enable them to holda large number of the balls, so that the wheel A. continues to rotatefor a pretty long time, always being supplied with fresh balls from theupper channels and discharging said balls into the lower channels.

The balls are raised from the lower to the upper channels by an elevatorC, which derives its motion from a wind wheel connected to the verticalarbor 6. consists of an endless belt f. which passes over two pulleys g.g..and which is provided with hooked fingers h. A rotary motion isimparted to the upper pulley g. by :a bevel gear 2". from the arbor c.of the wind wheel and the fingers 71 on moving with the belt in thedirection of the arrow marked near it in Fig. 1, catch into the slottedend of the lower channel B. and each pair of fingers takes up one of theballs, that may be deposited in said channel and on passing over the topof the upper pulley g. the ball are discharged into the upper channelB.through which they are conducted down to bucket wheel A. A retrogrademotion of the elevator is prevented by a spring pawl j, catching intothe teeth of a ratchet wheel is. on the axle of the upper pulley g. Theelevator will continue to raise the ball from the The elevator lower tothe upper channel as long as the wind hassufficient power to give motionto the wind wheel, and it is obvious that the wind wheel may be soproportioned, that the same is able with little wind to raise the ballssufficiently quick to keep up a supply for the bucket wheel and thatwhen a high wind prevails, the balls are raised much quicker thatnecessary to supply the bucket wheel, thus storing up the surplus power.of the high wind for such times, where the wind goes down altogether orwhere it has not sufiicient power to raise any of the balls. 1

With a wind wheel of sufficient power, and

with a sufficient number of balls the bucket Wheel can be kept in acontinugus and uniinclined. channels B. and elevator C. con- 7 formmotion. strueted and operatingin the manner and Having thusfullydescribed my invention,' for the purpose specified.
